Tiivistelmä
A tunable reflectance filter based on a metal-hydrogel-metal structure responsive to humidity and temperature is reported. The filter employs a poly(N-isopropylacrylamide)-acrylamidobenzophenone (PNIPAm-BP) hydrogel as an insulator layer in the metal-insulator-metal (MIM) assembly. The optical resonance of the structure is tunable by water immersion across the visible and near-infrared range. Swelling/deswelling and the volume phase transition of the hydrogel allow continuous reversible humidity- and/or temperature-induced tuning of the optical resonance. This work paves the way toward low-cost large-area fabrication of actively tunable reversible photonic devices.
